Specification of Letters Patent.

Patented May 14, 1907.

Application filed February 2, 1907. Serial No. 355.370.

To all whom, it may concern' Be it known that I, CHARLES-B. ALYEA, a citizen of the United States, residing at In dianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Anchors, of which the following is a specification.

My present invention relates to that class of anchors by means of which guy ropes or wires are secured; especially such as are used in holding telegraph and telephone poles against lateral strains.

The principal object of said invention is to produce ananchor for the purpose which can be embedded in the ground without excavating a hole of a size large enough to receive the anchor when its wings are distended but which can be inserted in a smaller hole and the wing then forced out into position.

Referring to the accompanying drawings which are made a part hereof, and on which similar reference characters indicate similar parts, Figure 1 is a side elevation of an anchor of the character in question, with the wings or plates folded, as when ready to insert in the hole provided for the purpose; Fig. 2 a similar view with the wings or plates extended as when 1n use, and Fig. 3 a horizontal view as seen when looking downwardly from the dotted line 3 3 in Fig. 2.

In this device the main anchor rod 21 is of substantially an ordinary form. At its lower end I provide a plate 22 whlch prevents it from being forced too far into the ground in the operation of lacing the anchor which will presently be escribed. This plate may be secured in position in any desired way. To prevent it from coming off after being placed in ositi on, I have shown a nut 23.

Secure to the main anchor rod 21 are stay bars 24, 24 the lower ends of which are provided with plate-supports, as hooks 25, to prevent the escape therefrom of the outer ends of the main anchor plates. These anchor plates 26, 26 are connected together at their inner ends by links 28 (there being preferably two of said links, one at each side of the main anchor rod) and the outer ends of said plates are slotted. The stay bars 24 pass through said slots, and the hooked ends thereof are beneath the plates when in operative position, as best shown in Fig. 1. The upper ends of the stay bars are pivotally connected to the main anchor rod by a pivot bolt 29.

In using this improved anchor the parts are first brought into the relation shown in Fig. 1. Then, a suitable hole having been dug in the ground, the anchor, in this condition, is inserted into said hole. The lower and outer ends of the main anchor plates being suitably curved and sharpened, they are then forced outwardly into the adjacent earth in any desired manner, as by pounding upon their upper ends with a suitable implement. They are thus presently forced from the position shown in Fig. 1 to the position shown in Fig. 2. The hole is then filled in the ordinary way, and the anchoring operation is complete.

By the use of this invention a considerable proportion of the ordinary excavating labor is avoided, and the anchor is engaged with the earth in its undisturbed condition, which lends much to the stability of position of the anchor. The structure is also very simple, and is inexpensive to manufacture.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, in an anchor, of a main anchor rod, stay bars pivotally connected thereto, and anchor plates connected at their outer ends to said stay bars and at their inner ends longitudinally slidable on said main anchor rod with their inner ends initially above the outer ends.

2. The combination, in an anchor, of a main anchor rod provided with a stationary head or plate on its lower end, stay bars pivotally connected to said rod, and anchor plates connected at their outer ends to said stay bars and at their inner ends mounted on said main anchor rod above said stationary head or plate.

3. The combination, in an anchor, of a main anchor rod, stay bars pivotally connected thereto and provided with hooked lower ends, and anchor plates having slots in their outer ends through which the stay bars extend and whereby they are connected to said stay bars, said anchor plates being also suitably connected at their inner ends to the anchor rod.

4. The combination, in an anchor, of a main anchor rod, anchor plates having their inner ends slidable relative to the main rod and initially higher than their outer ends and having slots in their outer ends, and stay bars connected to said rod and passing through the slots in said plates and provided With supporting ends for said :Q'plates, said main anchor rod being provided with a support for the inner ends of said plates.

5. The co1nbination,- in an anchor, of a main anchor-rod, stay-bars connected thereto, and anchor-plates hingedly-connected at their inner ends and supported by said stayrods at their outer ends, the connected inner ends of said plates being initially higher than the outer ends and longitudinally slidable relative to the main rod.

6. The combination, in an anchor, of a main anchor-rod, stay-bars connected thereto, a fixed support at the bottom of said main anchor-rod, anchor-plates hingedly I connected at their inner ends and adapted to slide longitudinally of the main rod from a position initially above the outer ends to rest upon said fixed support When in operative position, and supports carrying the outer ends of said anchor-plates.

In Witness whereof, I, have hereunto set my hand and seal at Indianapolis, Indiana, this thirtieth day of January, A. D. one thousand nine hundred and seven.

CHARLES B. ALYEA.
